A beautiful Power Bank with "trickle charge" about solar!

I have the Power Bank now has 4 months. They met as described in service. Man it can charge via USB and as a mobile charger for mobile phone etc. always have. My Nokia C3-01 so I can fully charge 3 times.
The charging speed via the integrated solar module is rather slow in our European light of equip. After 14 days in the sun, I had even charged purely on solar time almost completely (midsummer). There must be a clear and which can no longer be in there with the small dimensions of the solar cell even from a physical standpoint.
But otherwise a chic part! Therefore, from me five!
